Structure of the BAM complex and its implications for biogenesis of outer-membrane proteins

Nature Structural & Molecular Biology, 2016
In Gram-negative bacteria, the assembly of β-barrel outer-membrane proteins (OMPs) requires the β-barrel-assembly machinery (BAM) complex. We determined the crystal structure of the 200-kDa BAM complex from Escherichia coli at 3.55-Å resolution. The structure revealed that the BAM complex assembles into a hat-like shape, in which the BamA β-barrel ...

Finite-time synchronization for delayed complex-valued BAM neural networks

2017 Chinese Automation Congress (CAC), 2017
In this paper, finite-time synchronization for delayed complex-valued bidirectional associative memory (BAM) neural networks is investigated. Based on the finite-time stability and some inequality techniques, a synchronization criterion is provided to guarantee that the drive-response systems achieve synchronization in finite time, and the settling ...

Finite-Time Stability for Delayed Complex-Valued BAM Neural Networks

Neural Processing Letters, 2017
This paper studies the finite-time stability problem of complex-valued BAM neural networks with time delay. Firstly, based on a more suitable assumption for the complex-valued activation functions of the considered system, a tractable entire real-valued system is formed.

Substrate-dependent arrangements of the subunits of the BAM complex determined by neutron reflectometry

Biochimica et Biophysica Acta (BBA) - Biomembranes, 2021
In Gram-negative bacteria, the β-barrel assembly machinery (BAM) complex catalyses the assembly of β-barrel proteins into the outer membrane, and is composed of five subunits: BamA, BamB, BamC, BamD and BamE. Once assembled, - β-barrel proteins can be involved in various functions including uptake of nutrients, export of toxins and mediating host ...

Fixed‐time synchronization for complex‐valued BAM neural networks with time delays

Asian Journal of Control, 2019
AbstractIn this paper, the fixed‐time synchronization for complex‐valued bidirectional associative memory (BAM) neural networks with time delays is studied. Based on the fixed‐time stability, the Lyapunov functional method and some inequality techniques, a new criterion is presented to guarantee that the addressed systems achieve synchronization in ...

Dissipativity analysis of complex-valued BAM neural networks with time delay

Neural Computing and Applications, 2017
This paper is concerned with dissipativity analysis of complex-valued bidirectional associative memory (BAM) neural networks (NNs) with time delay. Some novel sufficient conditions that guarantee the dissipativity of complex-valued BAM neural networks (CVBNNs) are obtained by using the inequality techniques, Halanay inequality, and upper right Dini ...

The Bam (Omp85) complex is involved in secretion of the autotransporter haemoglobin protease

Microbiology, 2009
Autotransporters are large virulence factors secreted by Gram-negative bacteria. They are synthesized with a C-terminal domain that forms aβ-barrel pore in the outer membrane implicated in translocation of the upstream ‘passenger’ domain across the outer membrane.

Structure Determination of the BAM Complex Accessory Lipoproteins BamB–E

2015
Outer membrane protein biogenesis is a fundamental and essential process in all Gram-negative bacteria. The key players conducting this process are organized in the β-barrel assembly machinery (BAM) complex. This complex has recently attracted a lot of attention due to its importance in cell wall generation, maintenance, and the fascinating yet ...

Lagrange Exponential Stability of Complex-Valued BAM Neural Networks With Time-Varying Delays

IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2019
This paper is concerned with the Lagrange exponential stability problem of complex-valued bidirectional associative memory neural networks with time-varying delays. On the basis of activation functions satisfying different assumption conditions, by combining the Lyapunov function approach with some inequalities techniques, different sufficient criteria
